Security Bulletin
Summary
IBM App Connect Enterprise and IBM Integration Bus are vulnerable to a remote attacker due to jsonwebtoken (CVE-2022-23541, CVE-2022-23539, CVE-2022-23529, CVE-2022-23540). The resolving fix includes jsonwebtoken version 9.0.0. A mitigation is provided for IBM Integration Bus
Vulnerability Details
CVEID: CVE-2022-23541
DESCRIPTION: Auth0 jsonwebtoken could allow a remote authenticated attacker to bypass security restrictions, caused by an insecure implementation of key retrieval function. By sending a specially-crafted request, an attacker could exploit this vulnerability to forge Public/Private Tokens from RSA to HMAC.
CVSS Base score: 5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/242966 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2022-23539
DESCRIPTION: Auth0 jsonwebtoken could provide weaker than expected security, caused by an unrestricted key type issue. A remote authenticated attacker could exploit this vulnerability to allow legacy keys usage and launch further attacks on the system.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/242968 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:H/A:N)
CVEID: CVE-2022-23529
DESCRIPTION: Auth0 jsonwebtoken could allow a remote authenticated attacker to execute arbitrary code on the system, caused by improper input validation by the jwt.verify function. By sending a specially-crafted request using the key retrieval parameter, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/242967 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2022-23540
DESCRIPTION: Auth0 jsonwebtoken could allow a remote authenticated attacker to bypass security restrictions, caused by an insecure default algorithm flaw in the jwt.verify() function. By sending a specially-crafted request, an attacker could exploit this vulnerability to bypass signature validation.
CVSS Base score: 6.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/242969 for the current score.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
